A comparison of laser based ranging systems for AR/C category 1: Hardware [PDF]

open access: yes
This paper will present some aspects of the effect of inherent laser effects on the performance of CW-Tone modulated and FM-CW laser ranging techniques. It will be shown that performance of these techniques is affected in different ways by inherent laser

Exploring a Subpopulation of MASLD Associated With New Onset of CKD Using Supervised Clustering Techniques

open access: yesHepatology Research, Volume 56, Issue 5, Page 762-777, May 2026.
The supervised clustering of metabolic dysfunction‐associated steatotic liver disease (MASLD) using a SHapley Additive exPlanations (SHAP)‐converted matrix reveals distinct subpopulations that improved risk stratification for new onset of chronic kidney disease (CKD).

Principle and Design of a Vernier FM Radar System [PDF]

open access: yesIEEE Transactions on Aerospace and Electronic Systems, 1966
This paper describes the principle and the signal design of a proposed new FM radar system. In order to measure the surface characteristics of a small target at a long distance, or to discriminate among multiple targets, very accurate range or Doppler resolutions are necessary [1].
